文摘
A fine-sampling electromagnetic calorimeter prototype has been tested experimentally with tagged beams of negatively charged particles at the U70 accelerator at IHEP, Protvino. The energy resolution measured with electrons is . The position resolution for electrons is in the center of the cell. The lateral non-uniformity of the energy response to electrons and MIPs has turned out to be negligible. Obtained experimental results are in a good agreement with Monte Carlo simulations.
